==================
dot.kermrc:
Example for "~/.kermrc" Kermit init file for use with U-Boot
by Wolfgang Denk, 24 Jun 2001
flash_param:
"kermit" script to automatically initialize the environment
variables on your target. This is most useful during
development when your environment variables are stored in an
embedded flash sector which is erased whenever you install a
new U-Boot image.
by Swen Anderson, 10 May 2001
send_cmd:
send_cmd U_BOOT_COMMAND
"kermit" script to send a U-Boot command and print the
results. When used from a shell with history (like the bash)
this indirectly adds kind of history to U-Boot ;-)
by Swen Anderson, 10 May 2001
send_image:
send_image FILE_NAME OFFSET
"kermit" script to automatically download a file to the
target using the "loadb" command (kermit binary protocol)
by Swen Anderson, 10 May 2001
